php list files in directory and save to disk

I want to list the files in "archives/" and write the decoded array to disk (file name = "archives/events.txt") But what I have doesn't create that file.
xhr.send(data); // gives: Uncaught ReferenceError: data is not defined
What am I doing wrong?
function LISTevents () {
var xhr = new XMLHttpRequest();
xhr.open("POST", "json-events.php");
xhr.onload = function () {
console.log(this.response);
};
xhr.send(data);
return false;
}
json-events.php
<?php
// create list of events files in archives/* on server
$files1 = scandir('archives');
file_put_contents('archives/events.txt', print_r($files1, true));
?>

<?php
function list_contents($dir, $suffix) {
$contents = array();
$dir = realpath($dir);
if (is_dir($dir)) {
$files = scandir($dir);
foreach ($files as $file) {
if ($file != '.' && $file != '..' && $file != 'events.txt') {
if (substr($file, -strlen($suffix)) == $suffix) {
$contents[] = $file;
}
}
}
foreach ($contents as $key => $item) {
if (strlen($item) != 14) {
unset($contents[$key]);}
}
foreach ($contents as $key => $item) {
if (substr($item,0,1) != "2") {
unset($contents[$key]);}
}
}
$contents_json = json_encode($contents);
file_put_contents($dir . '/events.txt', $contents_json);
}
list_contents('archives','.txt');

Limit image upload size

I have a script for uploading images, it works fine but I would like to limit the image size to a maximum of 2 mb, I have tried a few things but without success, I am not one of the best at this so I would be very grateful for some help, follow the code
$(document).ready(function(){
$("#but_upload_w").click(function(){
var fd = new FormData();
var files = $('#file_w')[0].files;
if(files.length > 0 ){
fd.append('file',files[0]);
$.ajax({
url: 'host/profile/upload.php',
type: 'post',
data: fd,
contentType: false,
processData: false,
success: function(response){
if(response != 0){
$("#up-01").attr("value",response);
$("input").show(); // Link img
}else{
alert('failed');
}
},
});
}else{
alert("select");
}
});
});
<?php
if(isset($_FILES['file']['name'])){
$filename = $_FILES['file']['name'];
$location = "upload/".$filename;
$imageFileType = pathinfo($location,PATHINFO_EXTENSION);
$imageFileType = strtolower($imageFileType);
$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
$valid_extensions = array("jpg","jpeg","png");
$response = 0;
if(in_array(strtolower($imageFileType), $valid_extensions)) {
if(move_uploaded_file($_FILES["file"]["tmp_name"], "upload/".$newfilename)){
$response = "host/profile/upload/".$newfilename;
}
}
echo $response;
exit;
}
echo 0; ?>

if(isset($_FILES['uploaded_file'])) {
$errors = array();
$maxsize = 2097152;
$acceptable = array(
'application/pdf',
'image/jpeg',
'image/jpg',
'image/gif',
'image/png'
);
if(($_FILES['uploaded_file']['size'] >= $maxsize) || ($_FILES["uploaded_file"]["size"] == 0)) {
$errors[] = 'File too large. File must be less than 2 megabytes.';
}
if(!in_array($_FILES['uploaded_file']['type'], $acceptable)) {
$errors[] = 'Invalid file type. Only PDF, JPG, GIF and PNG types are accepted.';
}
if(count($errors) === 0) {
move_uploaded_file($_FILES['uploaded_file']['tmpname'], '/store/to/location.file');
} else {
foreach($errors as $error) {
echo '<script>alert("'.$error.'");</script>';
}
die(); //Ensure no more processing is done
}
}
Look into the docs for move_uploaded_file() for more information.

How do I submit form without page reload taking into consideration the php script?

So basically I have to work on this loan calculator loancalc.000webhostapp.com
I have looked at other pages on this site "how to submit form without page reload?" but this isn't completely relevant to what i'm working on. So far i've added this into the jquery part of the page...
jQuery('qis-register').on('submit', 'input', function(){
event.preventDefault();
var name = $("input#yourname").val();
var email = $("input#youremail").val();
if (name == ""){
$("input#yourname").focus;
return false;
}
else{
}
if (email == ""){
$("input#youremail").focus;
return false;
}
});
But i'm told there is also two other scripts that I need to work with, I'm not really too experienced with php so not sure what's going on, the two php scripts I have to work with are called quick-interest-slider.php and register.php,
//qis_verify_application in register.php

}
}

Do I have to edit any of the php and I also don't know what I have to write considering the php.

You can use what is called Ajax to submit the data to the server via POST.
Create a button and give it a class of qis-register, then give each of your input fields a class that matches it's name. Then just add that field to the data object that I have following the format within it.
jQuery(document).on('click', '.qis-register', function(){
var name = $("input#yourname").val();
var email = $("input#youremail").val();
if (name == ""){
$("input#yourname").focus;
}
else if (email == ""){
$("input#youremail").focus;
}
else{
jQuery.ajax({
type: "POST",
url: "your_php_here.php",
data: {
name:name,
email:email,
qissubmit:$(".qissubmit").val(),
qisapply:$(".qisapply").val(),
part2submit:$(".part2submit").val(),
},
done: function(msg){
console.log(msg);
}
});
}
});

Codeigniter jquery not working inside AJAX file upload

I have an AJAX file upload code in codeigniter. The Issue is that I changed the simple form submit to file submit. But After that, JQUERY has stopped working. The response is coming success, but at the same time, ajax error function is called. I don't know what's wrong with my code.
This is my controller.
public function ajax_add() {
$this->_validate();
$config = [
'upload_path' => './assets/game_images/',
'allowed_types' => 'gif|png|jpg|jpeg'
];
$this->load->library('upload', $config);
if ($this->upload->do_upload('image')) {
$file = $this->upload->data();
$file_name = $file['file_name'];
if ($file_name == '') {
$data['error_string'][] = 'Please upload an image.';
$data['status'] = FALSE;
echo json_encode($data);
exit();
}
} else {
$data['inputerror'][] = 'image';
$data['error_string'][] = $this->upload->display_errors();
$data['status'] = FALSE;
echo json_encode($data);
exit();
}
$data = array(
'title' => $this->input->post('title'),
'iframe' => $this->input->post('iframe'),
'status' => $this->input->post('status'),
'category_id' => $this->input->post('category_id'),
//'image' => $file_name
);
$insert = $this->game->save($data);
echo json_encode(array("status" => TRUE));
}
private function _validate() {
$data = array();
$data['error_string'] = array();
$data['inputerror'] = array();
$data['status'] = TRUE;
if ($this->input->post('title') == '') {
$data['inputerror'][] = 'title';
$data['error_string'][] = 'Game Title is required';
$data['status'] = FALSE;
}
if ($this->input->post('iframe') == '') {
$data['inputerror'][] = 'iframe';
$data['error_string'][] = 'Game Iframe is required';
$data['status'] = FALSE;
}
if ($this->input->post('status') == '') {
$data['inputerror'][] = 'status';
$data['error_string'][] = 'Status is required';
$data['status'] = FALSE;
}
if ($this->input->post('category_id') == '') {
$data['inputerror'][] = 'category_id';
$data['error_string'][] = 'Please select category';
$data['status'] = FALSE;
}
if ($data['status'] === FALSE) {
echo json_encode($data);
exit();
}
}
And this is my HTML
if (save_method == 'add') {
url = "<?php echo site_url('game/ajax_add') ?>";
} else {
url = "<?php echo site_url('game/ajax_update') ?>";
}
var formData = new FormData($('#form')[0]);
$.ajax({
url: url,
type: 'JSON',
data: formData,
async: false,
success: function (data)
{
if (data.status) //if success close modal and reload ajax table
{
$('#modal_form').modal('hide');
reload_table();
} else
{
for (var i = 0; i < data.inputerror.length; i++)
{
$('[name="' + data.inputerror[i] + '"]').parent().parent().addClass('has-error'); //select parent twice to select div form-group class and add has-error class
$('[name="' + data.inputerror[i] + '"]').next().text(data.error_string[i]); //select span help-block class set text error string
}
}
$('#btnSave').text('save'); //change button text
$('#btnSave').attr('disabled', false); //set button enable
},
error: function (jqXHR, textStatus, errorThrown)
{
alert('Error adding / update data');
$('#btnSave').text('save'); //change button text
$('#btnSave').attr('disabled', false); //set button enable
},
cache: false,
contentType: false,
processData: false
});

$.ajax({
type: 'POST',
url: url,
dataType: 'JSON',
contentType: 'application/json; charset=utf-8'

commands in chatroom & defining words after command

Okay basically I'm trying to have a action happen of alert('hi $message'); when a user enters the command /command lewis into the chatroom; In the alert I have stated the variable $message and this is the word followed by the command; for example /command $message. I have posted my script below; so basically what I'm trying to achieve is recognise when a user types /command followed by a $message into the textarea then perform an action.
Chatroom Javascript

var length = this.value.length;
// don't allow new content if length is maxed out
if (length >= maxLength) {
event.preventDefault();
}
}
});
// watch textarea for release of key press
$('#sendie').keyup(function(e) {
if (e.keyCode == 13) {
var text = $(this).val();
var maxLength = $(this).attr("maxlength");
var length = text.length;
// send
if (length <= maxLength + 1) {
chat.send(text, name);

the alert is only for the person who wrote the command in
Thankyou for any help, and I apologise for the lengthy question.
[edit] Sorry just re-read my question and I will just try and explain what I'm trying to achieve in abit more detail. So basically when a user inputs /command lewis the script would then perform an alert('Hi Lewis');. But then if a user was to enter /command john the alert would be alert('Hi John');.
The alert would be instead of posting the message to the chatroom.
